Prodn. of unlocking contact for safety deposit box and safe doors

摘要

The prodn. of unlocking contact involves digitally preprogrammed heat scanning values in the safety deposit box or safe lock. These digital values are compared with those of the heat conductivity test contact sleeve. The lock ensures an optimum protection against unauthorised opening.The heat conductivity is digitally programmed with differing rising pulses according to points and the pulse speed in the electronic component of the safety deposit box or safe. The heat conductivity electronic component is equipped with 6 heat conductivity sensing elements.
